Description

Corrosion-resistant reboiler Technical Field The utility model relates to the technical field of reboilers, in particular to a corrosion-resistant reboiler. Background The reboiler is a special heat exchanger which can exchange heat and has vaporization space. The feed level in the reboiler and the fractionation column level are at the same level. The liquid phase is provided from the bottom line into the reboiler. Typically 25-30% of the liquid phase is vaporized in the reboiler. The vaporized two-phase stream is sent back to the fractionation column with the vapor phase component of the return column passing upward through the tray and the liquid phase component falling back to the bottom. The application number CN202121289191.X discloses a corrosion resistant reboiler device comprising a bottom sealing mechanism, a bend and a tube side, a heat exchange mechanism, a buffer mechanism and a dispersion mechanism. The utility model can improve the corrosion resistance of the dispersion pipe and the bent pipe, prolong the service life, avoid perforation and improve the production safety. When the application is specifically used, the impact force of air flow is reduced by utilizing the dispersing mechanism, so that the dispersing mechanism is corroded and damaged, the dispersing mechanism needs to be replaced after long-term use, the dispersing mechanism is inconvenient to replace, and the reboiler use cost is improved as soon as the dispersing mechanism is replaced. Disclosure of utility model The present utility model aims to solve one of the technical problems existing in the prior art or related technologies. The technical scheme adopted by the utility model is as follows: The utility model provides a corrosion-resistant reboiler, includes heat exchange mechanism and anti-corrosion mechanism, heat exchange mechanism include the reboiler main part, cup joint in the lower ring flange on reboiler main part top, with the exhaust passage of lower ring flange top laminating, cup joint in the exhaust passage outside and through the last ring flange that bolt and lower ring flange are connected, anti-corrosion mechanism include with a plurality of metal medium plates of exhaust passage inner wall laminating, install in two metal curb plates of metal medium plate both sides, form in notch between metal medium plate and the metal curb plate, install in the metal medium plate outside and with the exhaust passage inner wall grafting a plurality of inserted bars, inlay and locate the magnet in the metal curb plate outside, magnet and exhaust passage inner wall magnetism inhale. Through adopting above-mentioned technical scheme, when the metal medium plate of single face, metal curb plate damage are serious, rotate two inserted bars at this face top, then the metal curb plate rotates to metal medium plate center, magnet and exhaust passage inner wall separation, then with the inserted bar on the metal medium plate with exhaust passage separation, can change metal medium plate, the metal curb plate of this face from this, effectively avoid whole change, reduced reboiler use cost.
